Mac Forum / Programming / Mac Programming / March 2008Vertical Orientation of NSSliderCell and usage within an NSMatrix
I'm thinking out loud on how to satisfy a need... I need a control which visually appears to be those of a graphic equalizer, or a series of slider cells with vertical orientation. However, in IB (v3) the slider cells are only horizontal? I guess I need to create a vertically oriented slider cell that I would drop onto each cell of an NSMatrix; this cell would be subclassed from NSSliderCell and somehow draw itself vertically; but how do get IB to use this custom cell? In prior xcode versions the notion of an IB palette is now gone in v3 but are there examples showing the steps I'll need?

Grab a vertical slider from the object library. Drag it into your window. Select it. Choose "Layout->Embed Objects In->Matrix" from the menu bar. HIt command-I to get the inspector window. Select the Attributes inspector, and use the steppers or the text field to enter the number of rows and/or columns you want in your matrix. -jcr > Grab a vertical slider from the object library.

Believe it or not, I had just found this out; the 'Embed in Matrix' option off the menu; that alone was worth moving to v3. I found that you'd want to setup the slider attributes first, replicate, then embed in the matrix. Thanks again.

Seem you can't un-embed them either. If I create individual sliders they work just fine, just not when assembled into a matrix. Has anyone tried this feature (of matrix embedding) successfully? p.s. I also for some reason can't get a level indicator to work at all so the problem might be in my nib somewhere? /los "I was a teenage net-random" > p.s.

All I did was create a new empty nib, drop in a window and place a level indicator in it and tried to %R (test it); it has no interaction at all; Similarly trying a slider (horz or vert) individually works fine but when encased into a matrix it becomes inoperative. Am I missing something on either account? Signature/los "I was a teenage net-random." ____________________________________________________________________ Carlos D.
